摘要 简要介绍通常的群组密钥管理方案,提出虚拟动态子群的概念,并基于该虚拟动态群组提出一个适应于虚拟动态子群的密钥管理方案,该方案可借助原来大群的密钥信息对虚拟动态安全子群进行管理,与LKH(logical key hierarchy)方案相比减少了很多的数据传输和密钥存储空间。 Key management was usually mentioned in general static group. Based on virtual dynamic subgroup, VDSG （virtual dynamic subgroup scheme） was proposed. The virtual dynamic subgroup was managed by using the key information of the group. Compared with LKH, the average cost of re-keying and the number of keys held are reduced largely.
